With the Bolder Boulder 41 days away, race director Cliff Bosley said Monday that events at the Boston Marathon will heighten security awareness, but since the 2001 terrorist attacks security at the Bolder Boulder — the third largest road race in the United States — has been a top priority.

“After the first set of terrorist attacks, our organizers, as well as those in the University of Colorado athletic department, became more heightened with our security concerns,” Bosley said. “Our No. 1 priority of the race is the safety of the participants and the spectators.”

Bosley said the 10K has “hundreds” of security people from a number of law enforcement agencies in the area as well as private security involved in race-day events.

“We are pretty high level on the security side,” Bosley said. “We have had numerous prerace meetings to this point, and we have more planned. Those will give us an opportunity to see specifically if we should do more or bolster anything.”

Last year, 51,681 runners signed up for the annual Memorial Day race, which finishes at Folsom Field on the CU campus.

“This is every race director’s worse nightmare,” said Rich Castro, who helps organize the Boulder race. “We’re twice as big and more concentrated than the Boston Marathon. At least we have protocols in place. … But how can you possibly plan for something like this?”

Cherry Creek Sneak director Pat Downing would not comment until there is more information, but said “we work closely with Denver police department. If it turns out to be intentional, we’ll coordinate with them for the event.” The Sneak, which drew nearly 10,000 runners last year, is scheduled for April 28.

“Dave McGillivray is probably the best-known race director of the world,” Downing said of the Boston boss. “Our thoughts and prayers go to that city.”
